When working with multiple image manipulation steps in PHP, what strategies can be employed to prevent errors and ensure accurate results?

When working with multiple image manipulation steps in PHP, it is important to properly handle errors and ensure accurate results. One strategy is to use try-catch blocks to catch any exceptions that may occur during the image processing steps. Additionally, you can check for errors returned by image processing functions and handle them accordingly to prevent unexpected behavior.

try {
    // Perform image manipulation steps
    // Example: resizing an image
    $image = imagecreatefromjpeg('image.jpg');
    $resizedImage = imagescale($image, 200, 200);
    
    // Save the resized image
    imagejpeg($resizedImage, 'resized_image.jpg');
    
    // Free up memory
    imagedestroy($image);
    imagedestroy($resizedImage);
} catch (Exception $e) {
    // Handle any exceptions that may occur during image processing
    echo 'An error occurred: ' . $e->getMessage();
}
